Description:Exquisitely composed and luminous of palette, Wayne Thiebaud's images of cakes, pies, candy, and other ubiquitous store-bought foods are meditations on what he has called the "tattletale signs" of our culture. Thiebaud turns a formidable talent on diverse subjects, but the gumball machines reproduced here bring us back to his pensive, good-humored preoccupation with the sweet stuff of American life.
